NOTES
The 'Ready' and 'Start' signals are independent of each other and either signal may be switched on first (contacts
closed). A board transfer occurs when both the 'Ready' and 'Start' signal are switched on (contacts closed). The
'Ready' and 'Start' signals are switched off (contacts open) 500msecs after both signals are switched on (contacts
closed).
